AEM - High Volume Fuel Rail for Honda Civic D16Y7 & D16Y8 Engines - 25-109BK

The AEM High Volume Fuel Rail 25-109BK is engineered to deliver consistent, high-capacity fuel flow for Honda Civic models equipped with D16Y7 and D16Y8 engines. Featuring a large 1/2-inch internal bore, this rail supports applications producing up to 1000 horsepower, ensuring reliable fuel delivery for both street and high-performance builds. Its enlarged bore design dampens backpressure pulses created by larger injectors, maintaining smooth operation and stable fuel pressure even in extreme conditions.

Constructed from CNC-machined billet aluminum and finished in black anodizing, the 25-109BK offers both exceptional strength and corrosion resistance. The rail includes a 1/8-inch NPT port for the addition of a fuel pressure gauge or nitrous system, providing flexibility for monitoring and tuning. A custom fuel line fitting allows direct connection to the factory fuel line, while the ends of the rail are pre-tapped for -6 AN or 9/16"x18 fittings—perfect for users upgrading to custom fuel setups.

Designed as a direct-fit upgrade for 1996–2000 Honda Civic models and 1996–1997 Civic del Sol trims, the AEM 25-109BK ensures easy installation while delivering a significant improvement in fuel flow capacity and pressure stability. It’s the ideal solution for enthusiasts looking to support turbocharged, naturally aspirated, or high-horsepower D16 engine builds with dependable and efficient fuel delivery.
